The cupped stone is a natural occurring Geo fact. The round ball is speculative unless found with other artifacts. Mother nature made many round balls. Good eye though. Flint chips is usually the first sign.

Welcome to tnet! I would of picked up that stone ball myself. It is one of the hardest things to prove as being a artifact imo. But they are neat anyway. Thanks for the post and I hope to see more of your finds, rock

Personal finds were on private property which I have permission to hunt.

Nice finds. You can find a lot of perfectly round rocks in areas that were near the edge of ancient seas. There is a place along SH-19 in Caddo County, Oklahoma where a bunch of these occur. People would go there and get them and use them as forms for shaping rawhide rattles. People still use them for that, but the rawhide rattle has pretty much become a sort of old school thing. Gourds and Calumet baking powder cans are the more current thing.
